> Such test filter out the obvious frauds.
if you need garbage like leetcode to filter out "obvious frauds" you got a whole lot of problems in your company/team/...
I took an online technical interview recently where there was a check-box they made you click before every section, promising you would not use AI to solve the test for you.
After they rejected me I had to point out that their test is selecting for the cheaters.
A colleague of mine came to me for advice. He wanted one of those high dollar jobs at a well-known MegaCorp. He knew a leetcode test was used by them. I suggested that his top priority was to study the leetcode books for the next 3 weeks. I told him those three weeks would be the best ROI he'd ever make.
He did so. He aced the test. He got the job with a huge offer. He agreed that the ROI was out of the park!
P.S. I'm curious what your test is for obvious frauds?
